PENCIL SHABPENERJ Application filed September This invention relatesto apencil sharp.- ener, and an object of the invention isto provide apencil sharpener having several advantageous features andcharacteristics of construction which are improvements generally overthe prior art, particularly over the disclosure of my pending application for Patent, Serial No. 96,738, filed March 23, 1926. I y 7 k Afurther object is to provide a pencil sharpener having a box of uniqueand improved construction for receiving the cut tings from a pencil.

A further bject is to provide in a pencil cuttings from-a pencil, andnovel and im-' proved interengaging means upon'said supporting frame andbox for detachablyconnecting said box to said supporting frame. lViththe above objects in View, as well as others which will appear as thespecifica: tion proceeds, the invention comprises the construction,arrangement and combination of parts as now to be fully described and ashereinafter to be specifically claimed, it being understood that thedisclosure herein is merely illustrative and meant in no wayin alimiting sense, changes in details ofconstruction and arrangement ofparts being permissible so long as within the spirit of the inventionand the scope of the appended claims; g

In the accompanying drawing forming va part of this specification,

being broken away and in section, of the box for receiving the cuttingsfrom a pencil;

Fig. 5 is an end view of the box as seen from the right in Fig. 4; i

Fig. 6 is a plan view of the inner end" piece of the box removedtherefrom; and

Fig. 7 is a plan View of a modified form of inner end piece for the box.

l/V threspect to the drawing'and the numerals ofreference thereon, 10denotes the supporting frame of the pencil sharpener,

including a base ll with screw holes for-- screws 12 and an upright orstandard 13' upon the base. The supportingframe'i s as disclosed acasting, 14: representing a flange or rib about the side margins ofthe'bas-e and upright or 7 standard for strength.

Numeral 15 represents a cutter having a tapered recess 16: for thereception of the end of a pencil to be sharpened 17 is a longitudinalslot in thecutter, and 18 is a blade attached toithecutter by a screw19, the edge of the blade extending into the tapered recess 16. a I 4 vThe inner end of the cutter .15 is'provided with a stud 20 mounted in abearing 21 integral with the supporting frame and at the sidethereofopposite the cutter. A crank 22 has a tight fit upon the end 23of the stud set said metal and thus lock the crank upon the stud, aswill be understood.

Numeral 25 denotes a box detachably as sociated with the upright 13 andadapted to receive cuttings from a pencil inserted in the taperedopening of the cutter 15 to be sharpened. The box 25, as disclosed,consistsof a. casting 26 and'afront wall 27 of metal which isremovablyassociated with said casting 26. That is to js'ay,'the casting 26constitutes the base 28, the side walls 29', the top wall 30, and therear wall 31 of the box, and a blank of metal constitutes the frontwall27 thereof. The rear wall 31 has a clearance opening 32 adapted to alignwith the tapered opening of the cutter 15 so that pencils to besharpened may be inserted in the cutter. The front wall 27 of the boxextends upwardly from the base 28 thereof a distance slightly less thanhalf of the height of the box, the upper edge 33 of said wall 27 beingbetween the side walls 29 of the casting and preferably beinghorizontally disposed in use. The side walls 29 of the cast:

mg are desirably parallel and are vertical in use, and the base 28 andtop wall 30 are The plate of metal 27 is of outline to snugly fit withinthe open end of the casting adjacent the base 28 thereof, 34representing lugs upon said plate adapted to seat in depressions 35 111the free edges ofl the side walls 29, and 36 denoting a lug upon saidplate adapted to seat in a do.

28. Numeral 38 indicates the metal of the free edges 29 and base 28adjacent the lugs 34 are struck to upset plate 27 to the casting, aswill be obvious.

box 25 include locking members 39 adapted to detachably enter verticalelongated slots 40 in the upright or standard 13, said upright orstandard havmg two sets of elon-l gated slots 40, one set to be usedwhen the pencil sharpener is upon a horizontal support A (Fig. 1), andthe other set to be used when the sharpener is upon a vertical support B(Fig. 2). Each member 39 includes a downwardly disposed hook 41providing a notch 42 between the hook and a side wall 29, the front andrear walls 43 of the notch being preferably vertical and spaced apart adistance approximately equal to the thickness of the material of theupright or standard 13.

As disclosed, the plate 27 is notched a 44 to provide a spring 4:. bentoutwardly away from the casting 26'. A protuberance 46 upon the springis adapted to enter a depression 47 in the upright 13, there being twodepressions 47 in said upright, one to be entered by the protuberancewhen the sharpener is upon a horizontal support, as in Fig. 3, and theother to be entered by said protuberance when the sharpener is upon avertical summrt, as in Fig. 2.

In Fig. 7 the plate 27 is with ut ill? 12 cial spring 45 andprotuberance 46. said plate 27 being here adapted to itself serve as thespring member.

The manner of d-eta-chably associating the box 25 with the upright 13will be apparent.

The locking members 39 are first inserted in the slots 40 until thenotches 42 align with the upright or standard, and the spring 45 is madeto engage the adjacent face oflthe upright or standard with pressure;The box being so situated against the upright, it is forced to slidedownwardly until the bases f the notches 42 engage the lower edges ofsaid metal and lock the standard until said walls 43 are clear of saidupright or standard. lVhen the box is "suspended upon the upright orstandard, the preferably smoothly curved about as shown.

cutter is in the box, the wall 27 is clear of the cutter, and theopening of the cutter {aligns with the clearance opening 32 of thejlrear wall of the box.

It is to be understood that the plate 27 .l r ,could have the specialsplmg 4.) with pro tuberance 46 omitted, or the plate 27 could lg have aprotuberance such as that denoted 46. pression 37 in the free edge ofthe base locations where glwhat I claim as new and desire to secure ofthe side walls'ifiby Letters Patent is:
